Module
d7y.io/dragonfly/v2
github.com/dragonflyoss/dragonfly

Description:

Impact

The access control mechanism for the Proxy feature uses simple string comparisons and is therefore vulnerable to timing attacks. An attacker may try to guess the password one character at a time by sending all possible characters to a vulnerable mechanism and measuring the comparison instruction’s execution times.
The vulnerability is shown in figure 8.1, where both the username and password are compared with a short-circuiting equality operation.

if user != proxy.basicAuth.Username || pass != proxy.basicAuth.Password {

It is currently undetermined what an attacker...
